Ток небаланса и ток пульсаций при несимметричном напряжении
For three-phase system with an asymmetric sinusoidal voltage at the point of connection asymmetrical loading two orthogonal decomposition of full three-phase current are considered. The first expansion is associated with the expansion of the current along the voltage vector and provides two componen...

Unbalanced current and the pulsating current at asymmetrical voltage
Yu.O. Sirotin,
National Technical University "KhPI",
Frunze, 21, Kharkiv, 61002, Ukraine.
For three-phase system with an asymmetric sinusoidal voltage at the point of connection asymmetrical loading two
orthogonal decomposition of full three-phase current are considered. The first expansion is associated with the
expansion of the current along the voltage vector and provides two components: the balanced current and the
unbalanced current. The second expansion is associated with the expansion of the current along the (complex)
conjugate of the voltage vector and gives the two components: the pulsating current and the non-pulsating current. Two
power equations are obtained. It is shown how these expansions are related to each other. The results of numeric
modeling are given. References 7.
Key words: three-phase system, instantaneous power; active and reactive, complex, apparent power; pulsation power,
unbalanced load, power equation, power factor, unbalanced mode, asymmetrical voltage.
